All astronauts and their qualifications

In the history of space exploration, astronauts have always been some of the most highly qualified individuals. In the early days of NASA, all astronauts had remarkable educational backgrounds, with most holding master's or doctorate degrees in various fields.

However, not all astronauts were trained pilots. Only two of them were jet pilots, while others came from diverse scientific backgrounds. This created a unique challenge for those astronauts who had no flight experience. To ensure their safety and competence in space missions, they had to undergo one year of intensive flight training.

This rigorous training program included simulation exercises, classroom instruction, and hands-on practice in flight simulators. By the end of the training period, all astronauts were proficient in piloting spacecraft and handling emergency situations.
